"In June of this year, Sesame Workshop received a communication from a young man who alleged that he had a relationship with Kevin Clash beginning when he was 16-years-old," a rep for Sesame Street said in statement sent to FOX 411. "This was a personal relationship, unrelated to the workplace. We took the allegation very seriously and took immediate action."

The accuser is being represented by Andreozzi and Associates, a firm that represented one of Jerry Sandusky's rape victims.

"Elmo is bigger than any one person and will continue to be an integral part of Sesame Street to engage, educate and inspire children around the world," Sesame Street's rep said.

Still, Clash is not just a behind-the-scenes voice. In 2011, he starred in the documentary "Being Elmo," which got rave reviews and won the Special Jury Award at the Sundance Film Festival.

"When I was nine years old, it was just a dream that I had: Wow, I wish that I could work with the Muppets" Clash says in the film's trailer.

The movie follows Clash's journey to become the ticklish puppet, describing a child who sewed his own dolls and moved to New York after high school to try and land a role as a puppeteer.

Clash appeared on several shows to promote the film around the time of it's Sept. 2011 release, putting a face to the distinct Elmo voice.

In earlier years, he also appeared in several interviews with Australian TV personality Rove McManus and mentioned he has a daughter.

Clash also co-authored a book about his journey in 2006 titled "My Life as a Furry Red Monster: What Being Elmo Has Taught Me About Life, Love and Laughing Out Loud."
